I don't have an amd64 system, so there is no way I can provide a tested
patch.  I think Diego Petten??'s patch that he already sent to the list is
probably the best that one can hope for.  The asm code used in cabac.h
isn't suitable for a x86-64 DSO.  In order to use an asm cabac in a x86-64
DSO, new asm must be used, and something as simple as changing MANGLE isn't
enough to do it.  IMHO, tt hardly seems worth the trouble.

But that 4GB space can be anywhere in the 64-bit address space.
